Cover plate type protection system with detection function for foundation pit

Abstract

The invention relates to the technical field of foundation pit protection, in particular to a cover plate type protection system with a detection function for a foundation pit. The cover plate type protection system comprises a bottom plate with an opening, the opening of the bottom plate is provided with a frame, and the frame is provided with two cover plates and a first moving mechanism for controlling opening and closing of the cover plates; a groove is formed in the cover plate, a first conductive plate is arranged in the groove, a conductive column and a first spring are arranged on the first conductive plate, a second conductive plate is arranged on the first spring, and a first insulating plate is arranged on the second conductive plate; a friction plate is arranged below the cover plate, a rack is arranged below the friction plate, the cover plate is provided with a limiting sliding rail matched with the rack, and the first moving mechanism is provided with a first gear meshed with the rack; a telescopic mechanism for controlling the friction plate to move and a first motor are arranged on the cover plate; the first conductive plate, the second conductive plate, the conductive column and the first motor can form a closed loop; and the detachable electric foundation pit cover plate prevents people in the foundation pit from being injured by objects on the cover plate in the opening process of the cover plate, improves the operation safety of the foundation pit, and can be widely applied to the field of foundation pit protection.

Description

Technical field [0001] The present invention relates to a foundation pit technical field, in particular, it relates to a foundation having a plate-type protection system detecting function. Background technique [0002] When the excavation work, in order to avoid falling rock outside the pit, falling objects and other tools to the slide injured pit pit construction workers, often used for the cover of the pit block; construction workers outside the object off the pit in the pit occurs during operation fall onto the cover, when construction workers job is complete, open the cover, the cover objects may fall on the cover with the open pit to fall, leading to construction workers injured in the course of the cover that opens. Inventive content [0003] For open pit present in the prior art protective cover on the lid to fall to the object may occur during a pit, the pit injured worker further problem, the present invention provides a detecting function having a pit lid plate protec...
